The Crossed Sabres ( House of Winslow (Paperback) #13 ) by Gilbert Morris

The 13th installment of the compelling series--and sequel to The Final Adversary. Left with a baby girl when his wife dies in childbirth, Thomas Winslow secures a post with the Department of Indian Affairs just as President Grant orders a halt to the Indian attacks on the Northern Plains. General Custer hears of Tom's experience and offers his a job as scout on his next campaign: Little Big Horn.
